Embodiment Construction

[0019] A polyvinyl chloride friction material, which is composed of the following parts by weight:

[0020] Polyvinyl chloride 140, ethyl orthosilicate 6, 1,3,5 trimethylbenzene 0.01, melamine 37, 37% formaldehyde aqueous solution 50, triethanolamine 0.2, alkylphenol polyoxyethylene ether 0.3, dihydrocarbyl pentasulfide RC25402, potassium hexatitanate whisker 1, titanate coupling agent kt1050.3.

[0021] A method for preparing the polyvinyl chloride friction material includes the following steps:

[0022] (1) Mix 10% of the weight of the above-mentioned polyvinyl chloride with 1,3,5 trimethylbenzene, add it to a 27% hydrochloric acid solution 70 times the weight of the mixture, and send it to a constant temperature water bath at 36°C. Stir at 200 rpm for 4 hours, add dropwise the above-mentioned ethyl orthosilicate, stir and react for 24 hours, discharge the material, dry at a constant temperature of 100°C for 20 hours, and then calcinate at 550°C for 4 hours to obtain a mesoporous ...

Abstract

The invention discloses a polyvinyl chloride friction material. The material is prepared from, by weight, 140-170 parts of polyvinyl chloride, 6-8 parts of tetraethoxysilane, 0.01-0.02 part of 1,3,5-trimethylbenzene, 37-40 parts of melamine, 50-60 parts of 37-40% formalin, 0.2-0.3 part of triethanolamine, 0.3-0.5 part of alkylphenol ethoxylates, 2-3 parts of dialkyl pentasulfide RC2540, 1-2 parts of potassium hexatitanate whiskers, 0.3-1 part of a titanate coupling agent kt105. Resin is coated with dialkyl pentasulfide and potassium hexatitanate whiskers, the mechanical property of the resin matrix can be improved, the service life can be prolonged, some loads can be borne in the friction process, the adhesion on the surface of a friction pair is reduced, heat changes of the resin matrix are stopped, the friction and wear resistance is improved, and the comprehensive performance of a finished material is improved.

Description

Technical field [0001] The invention relates to the technical field of friction materials, in particular to a polyvinyl chloride friction material and a preparation method thereof. Background technique [0002] Tribological materials can be divided into anti-friction materials, wear-resistant materials and friction materials according to the working conditions and requirements of friction elements. According to the type of material, it is divided into metal tribological materials, inorganic non-metallic tribological materials and polymer tribological materials. The perishable characteristics of metal materials hinder its application in special occasions such as navigation or chemical industry; ceramic materials Brittleness is more serious hindering its application, especially the residual pores of ceramic materials in the sintering process have a considerable impact on performance; polymers and their composite materials have excellent physical and chemical properties, light weigh...
